low iscsi storage space
by Leonardo Costa 10 Aug '21

10 Aug '21

Hello. I'm having a problem that I can't solve, I have 20Tb of space on Ovirt but on my DELL SCV 3000 storage, only 5Tb free on the volume. It seems to me that the deleted machines are not removing the disks in the storage iscsi. Could anyone help?

Major network issue with 4.4.7
by Andrea Chierici 10 Aug '21

10 Aug '21

Dear all, I've been using ovirt for at least 6 years and only lately I've stepped into a weird problem that I hope someone will be able to give help. My hardware is: - blade lenovo for hosts, with dual switch - dell equallogic for iscsi storage, directly connected to the blade switches - The two host network cards are configured with bonding and all the vlans are accessed from it (mtu 9000) - all the hosts and ovirt engine have firewalld service disabled) My engine is hosted on a separate vmware vm (I will evaluate the self hosted engine later...). I want to stress the fact that for years this setup worked smoothly without any significant issue (and all the minor updates were completed flawlessly). A few weeks ago I started the update from the rock solid 4.3 to the latest 4.4.7. I began with the manager, following the docs, installing a new centos8 vm and importing the backup: everything went smootly and I was able to get access to the manager without any problem, all the machines still there :) I then began updating the hosts, from centos7 to centos8 stream, one by one. Immediately I noticed network issues, with the VMs hosted on the first updated host. Migrating VMs from centos8 host to other centos8 quite often fails, but the main issue is this: *if I start one of the VMs on the centos8 host, they have no network connectivity. If I migrate them to a centos7 hosts the network starts to work, and if I migrate the VMs back to the centos8 host, the network keeps working.* I am puzzled and can't understand what's going on. Generally speaking all the centos8 hosts (I have 6 in my cluster, and now 3 are centos8 while the rest is still centos7) seem to be very unstable, meaning that the VMs they host are quite often showing network issues and temporary glitches. Can someone give a hint on how to solve this weird issue? Thanks, Andrea -- Andrea Chierici - INFN-CNAF Viale Berti Pichat 6/2, 40127 BOLOGNA Office Tel: +39 051 2095463 SkypeID ataruz --

live merge of snapshots failed
by g.vasilopoulos＠uoc.gr 10 Aug '21

10 Aug '21

Hello I have a situation with a vm in which I cannot delete the snapshot. The whole thing is quite strange because I can delete the snapshot when I create and delete it from the web interface but when I do it with a python script through the API it failes. The script does create snapshot-> download snapshot-> delete snapshot and I used the examples from ovirt python sdk on githab to create it ,in general it works prety well. But on a specific machine (so far) it cannot delete the live snapshot Ovirt is 4.3.10 and the guest is a windows 10 pc. Windows 10 guest has 2 disks attached both on different fc domains one on an ssd emc and the other on an hdd emc. Both disks are prealocated. I cannot figure out what the problem is so far the related engine log: 2021-08-03 15:51:00,385+03 INFO [org.ovirt.engine.core.bll.snapshots.RemoveSnapshotSingleDiskLiveCommandCallback]

Storage Domains for a VM from Template
by Shantur Rathore 09 Aug '21

09 Aug '21

Hi all, I have multiple storage domains in my DC. One is backed up that has templates and another one which isn't backed up and I want to use it for VM instances of the template. I cannot find an option to create the VM from a template and use a storage domain other than where the template is stored. Is it even possible? Thanks, Shantur

any configuration when clients can't directly access oVirt cluster?
by yam yam 09 Aug '21

09 Aug '21

Hello, Under my environment, clients must go through a proxy to reach the oVirt cluster(physical nodes), so that I applied DNAT rules for engine and VM IPs to clients. but there were still some issues like VNC console(+browser) don't work, and I'm not sure other features work well. so, I'm wondering whether there is any oVirt configuration or some guides for such case using the proxy. Thanks,

ISO Upload in in Paused by System Status
by louisb＠ameritech.net 09 Aug '21

09 Aug '21

I'm attempting to upload an ISO that is approximately 9GB in size. I've succssfullly started th upload process via the oVirt Management Console/Disk. The upload started however, it now has a status of "Paused by System". My storage type is set to NFS Data. Is something happing the back ground that contributing to the "Paused by System"? I have mor the 84TB of space available so I don't think it is a space issue. Is there something that I need to do? At this time I'm going to wait and see if it moves forward on its own. Please provide me with any help or direction. Thanks

fencing and (virtual) power button pression reaction
by Gianluca Cecchi 07 Aug '21

07 Aug '21

Hello, in RHCS we have the fencing concept for targets very similar to the oVirt ones: avoid data corruption and also fast react to problematic hosts situations. The implementation is quite similar to the oVirt one, with several fencing agents sometimes common, like fence_ipmilan. In RHCS documentation there is a chapter describing how to configure hosts so that they don't react to power button pressure. This guarantees that failover is as fast as possible, and also that the same host to be fenced, could create more damages if it reacts and begins the shutdown procedure instead of simply powering off. See: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/ht… It seems to me that oVirt / RHV lack this feature. Inside oVirt NGN and also RHVH-H, the /etc/systemd/logind.conf file is not configured with an entry of type HandlePowerKey=ignore So in some cases of tests I'm doing, I see in its virtual console that the to-be-fenced host begins its OS shutdown flow when it detects the power button pressure. Typically after 2-3 seconds the system powers off and then on again, but I also saw about 10 seconds delays in one case. I have opened a case (number 03002278) for my RHV products, but I would also like to get your comments here if I'm wrong with my considerations. Gianluca
